Implements hook_entity_base_field_info().

File

./token.module, line 646

Enhances the token API in core: adds a browseable UI, missing tokens, etc.

Code

function token_entity_base_field_info(EntityTypeInterface $entity_type) {

  // We add a pseudo entity-reference field to track the menu entry created
  // from the node add/edit form so that tokens generated at that time that
  // reference the menu link can access the yet to be saved menu link.
  // @todo Revisit when https://www.drupal.org/node/2315773 is resolved.
